  • How can I unbind JQZOOM in my JQuery Script?

    - by Andy Barlow
    Hello, I have this script at the moment, which changes an image when a thumbnail has been changed. I then want JQZOOM to be added to that new image. However, if I put it inside the Onclick event, it gets slower and slower the more times you click on it... I guess because its running multiple instances. Is there anyway to unbind the JQZOOM from something then rebind it to something else? Here is my jquery at the moment: var options = { zoomWidth: 400, zoomHeight: 325, xOffset: 25, yOffset: 0, position: "right", lens: true, zoomType: "reverse", imageOpacity: 0.5, showEffect: "fadein", hideEffect: "fadeout", fadeinSpeed: "medium", title: false }; $('.jqzoom').jqzoom(options); $('.single-zoom-image').click ( function () { $('#bigProductImage').attr("src", $(this).attr("zoom")); $('.jqzoom').attr("href", $(this).attr("extrazoom")); }); Thanks in advance if anyone can help me. Cheers!

  • If/else isn't working properly

    - by luckytaxi
    I have a validation function I'm using inside of codeigniter. function valid_image() { if ( ($_FILES["file"]["type"] != "image/jpeg") || ($_FILES["file"]["type"] != "image/gif") ) { $this->form_validation->set_message('valid_image', 'Wrong file type..'); return false; } else { return true; } With just the "image/jpeg" part in the if statement it works fine. If I try to upload anything other than a jpg file it fails. If I run the code above, it fails with both a jpg or a gif file. And before someone says "why not use the upload class," I can't. I'm saving my pics directly into MongoDB, so the upload class doesn't help much.

  • Why does UIImageView "darken"/saturate PNG images, and can I stop it?

    - by Ben
    I have a PNG file in a UIImageView, and next to that I have an EAGLView which displays the continuation of that same image (long story) as a texture, carved from the same original PNG. The point is, that these images, which should match up flawlessly, actually have somewhat differing color saturation. Normally I'd blame my handling of the PNG texture load in GL, but when I hold Preview (with the PNG) up to the iPhone simulator, it's GL that's spot on, and the UIImageView that's wrong! It's taken the image and made it ever-so-slightly more saturated. The image view is opaque with 100% alpha. I verified this on a clean UIImageView with another PNG file when put next to Preview. Anyone know what's up?

  • Remove Custom UINavigationBar

    - by Lithium
    Hi, I've customized my UINavigationBar with an image like that : @implementation UINavigationBar (CustomImage) - (void)drawRect:(CGRect)rect { UIImage *image = [UIImage imageNamed: @"NavigationBar.png"]; [image drawInRect:CGRectMake(0, 0, self.frame.size.width, self.frame.size.height)]; } @end When I launch a video my custom NavigationBar (with the picture) is on the top or I would like to have the default navigationBar style when I'm playing a video. I tried to hide the navigationBar with [self.navigationController setNavigationBarHidden:YES animated:animated]; but it just remove the navigationBar in my controller but I still have the NavigationBar.png when I'm playing a video. I tried to set the barstyle but it doesn't work either ... self.navigationController.navigationBar.barStyle = UIBarStyleDefault; Could you help me ?

  • Adding a dynamic-height UITableView into a scrolling view?

    - by Greg
    Hello all – I'm getting into iPhone development and have hit my first confusing UI point. Here's the situation: My app is tab-based, and the view that I'm confused about has a static featured content image at the top, then a dynamic list below into which X headlines are loaded. My goal is to have the height of the headline table grow as elements are added to it, and then to have the whole view scroll (both featured image on top and headline list below). So, I guess my question comes in two parts: 1) First, how do you set up a dynamic-height table view that will grow as cells are added to it. So far I've only been able to have my tables handle their own scrolling. 2) Then, what is the root NIB view that the featured image and the table should live in to enabled scrolling? I've dropped oversized content into a UIScrollView now, although did seem to have any success with having it automatically scroll. Thanks in advance for any help on this subject!

  • UIScrollView content to track a CAKeyFrameAnimation along a path

    - by CMLloyd
    In my App I have a full-screen UIScrollView where the content is a UIImageView containing a map image which is about 2000px square (i.e. larger than the UIScrollView). Currently, I plot a path across the map and animate a "beacon" image along it using a CAKeyFrameAnimation, which works great. What I would like to be able to do is to make the UIScrollView content move with the animation in such a way as to keep the beacon image in the centre of the screen (giving the user the impression of tracking along the path). Any suggestions on how I might achieve this?

  • getting window screenshot windows API

    - by Oliver
    Hi, I am trying to make a program to work on top of an existing GUI to annotate it and provide extra calculations and statistical information. I want to do this using image recognition, as I have learned a fair amount about this in University using Matlab and similar things. I can get a handle to the window I want to perform image recognition on, but I don't know how to turn that handle into an image of that window, and all its visible child windows. I suppose I am looking for something like the screenshot function, but restricted to a single window. How would I go about doing this? I suppose I'd need something like a .bmp to mess about with. Also, it would have to be efficient enough that I could call it several times a second without my PC grinding to a halt. Hopefully this isn't an obvious question, I typed some things into google but didn't get anything related.

  • jQuery Animate width to the left and up

    - by efru
    Hi all- I'm trying to animate an image's width and height properties. Currently the image (as expected) animates to the right and down, however I'd like for the animation to occur to the left and upwards. Here's my current code : http://jsfiddle.net/7UbYy/ I've read a few other posts on this subject which all refer to setting a marginLeft or left property but I can't seem to get the desired effect. I need the image to animate to the left and upwards while remaining in place. Let me know if this is possible...I can't seem to think of a way to do it right now.. Thanks in advance. Appreciate it.

  • jQuery Custom Gallery and jCarousel problem

    - by steve
    Active site can be seen here: http://www.studioimbrue.com/index2.php There are currently two small problems with the coding. First: when the page loads and you attempt to click on one of the large images to advance, nothing happens. Once a thumbnail is clicked, the click functionality of the large image comes available. I'm trying to fix it so when the page loads, the user can just start clicking the large image. Second: when an image is clicked, the thumbnail highlight changes. The only problem there is once it gets past 4, the "current" thumbnail needs to be seen, thus the carousel should go to that one. Right now the code for that is nextThumb.closest('.thumbscontainer').jcarousel('next'); but that makes it scroll every time you click. Thanks for any help

  • Flex datagrid multiple rows single file

    - by Vish
    Hi, I have a flex datagrid with 3 columns. The first column contains the image name(unique key). The other two columns have username and size details. I want to split the username into lastname, firstname, address and some other stuff. Can we have multiple rows in the grid for one image? Tried multi-line, it works but we need to keep adding spaces and its cumbersome. Since each row in the flex datagrid is represented by one index in the XMLList which is enumerated, is there a way to have more than one row assigned to one image and shown in the grid? something like this.. Thanks, Vish.

  • Working with images in asp.net MVC ViewMasterPage in design mode

    - by amit.codename13
    While designing a master page i am adding a number of images to it. I have an image tag inside the master page, <img src="../../Content/Images/img19.jpg" class="profileImage" /> When i run my app, the image doesn't show up in the browser because the src path in the page that browser gets is same as in the master page. ie. "../../Content/Images/img19.jpg" But it should have been "Content/Images/img19.jpg" If i correct the src path in master page as <img src="Content/Images/img19.jpg" class="profileImage" /> Then I can see the image in the browser but not in design mode. Any help is appreciated.

  • print css: fit in one page

    - by user281521
    Hi. In my page there's only one image. Kind of 1500x3000 px. In the printer, I need that this image's maximum width to be the width of the page, so I did: width 100% in the css, and it works. But the height... the old bullshit of height 100% will never work. Because it always will be 100% of the parent container, then someone must have height defined. Or html or body. So, my question is: make this image fit in one page. Any ideas?

  • Change Titlewindow close button

    - by Cameigons
    I'm working with Flex 3.4 SDK. I need to change the default close button image from a TitleWindow. So what I'm doing is defining a CSS selector, like this: TitleWindow{ close-button-skin: Embed('assets/close.png'); border-color: #FFFFFF; corner-radius: 10; closeButtonDisabledSkin: ClassReference(null); closeButtonDownSkin: ClassReference(null); closeButtonOverSkin: ClassReference(null); closeButtonUpSkin: ClassReference(null); } The problem is: the result image is totally squeezed beyond recognition. Probably because the image dimensions are 55x10 pixels (much wider than the default closebutton square-like dimensions) and flex forces it to fit that size. Would anyone know how to go about fixing that?

  • Scala Lift - Robust method to protect files from hotlinking

    - by sirjamm
    I'm attempting to implement a way to stop hotlinking and/or un-authorised access to resources within my app. The method I'm trying to add is something I've used before in PHP apps. Basically a session is set when the page is first called. The images are added to the page via the image tag with the session value as a parameter: <img src="/files/image/[handle]?session=12345" /> When the image is requested the script checks to see if the session is set and matches the provided value. If the condition is not met the serving page returns null. Right at the end to the code I unset the session so further requests from outside the scope of the page will return null. What would be the best implementation of this method within the lift framework? Thanks in advance for any help, much appreciated :)

  • Position text in top of a dinamically generated map area of type poly

    - by Guillermo Vasconcelos
    Hi, I have a web page with a dynamically generated image map (from a server side charting tool that I have no control over). I have a value for each area in the title attribute that I want to display on top of the image. I could dynamically generate span elements with absolute positioning, but I'm not sure how to calculate the "center" of a poly shaped area to use as coordinates. Is there an easy way to create texts for image map areas? a JQuery plug in perhaps? Do you know a good way to calculate the center of a poly area? Do you have any other suggestions? Thanks, Guillermo

  • Changing the value of an NSImageView when it is edited via the control

    - by Septih
    Hello, I have an NSImageView which is set to editable. I would like to be able to revert to a default image when the user deletes the image. I've tried changing the value that the NSImageView is bound to in the setter, but the getter is not called afterwards, so the NSImageView is blank, despite the bound value being set to another image. Here is the setter code: -(void)setCurrentDeviceIcon:(NSImage *)newIcon { [self willChangeValueForKey:@"currentDeviceIcon"]; if(newIcon == nil) newIcon = [currentDevice defaultHeadsetIcon]; currentDeviceIcon = newIcon; [self setDeviceChangesMade:YES]; [self didChangeValueForKey:@"currentDeviceIcon"]; } How should I make the NSImageView update it's value? Thank You.

  • How do I add a textbox to my other jQuery click function?

    - by marcamillion
    Right now, my script adds a box to the cursor when I click on an image, as can be seen in the following code. Please note, this is jQuery. $(function() { var tag_box = $("<div>").appendTo("body").css({"width":"40px", "height":"40px", "border":"4px solid #000000", "position":"absolute", "display":"none", "padding":"15px"}); $("#image-wrapper").live('click', function(e){ tag_box.css({"left": e.pageX - 40, "top": e.pageY - 40, "display":"block"}); }); I would like to add a text field to appear right below that tag_box on that same click. I tried to do this, but it hasn't worked out like I thought it would: var comment_box = $("<label> Comment: <input type='text' name='comment' autocomplete='off'></label>"); $("#image-wrapper").live('click', function(){ $("body").append(comment_box); }); Any assistance you can give me, would be greatly appreciated. Thanks.

    I've run into a major display problem on newly installed fedora 11, on my 6 years old pc which runs a pentium4 2.4 GHz processor, 1 gb ddr ram, intel 845 motherboard with integrated graphics card. When i open an image or play a video, my complete screen turns garbled. I simply cannot make out whats on my screen. With difficulty i have to close the image/video window and move around the folder window to clean the screen image. Is it because of my display drivers? How can i fix it? I also ran into mp3 plugins and flash issues which i was able to resovle. I'm new to linux, the sole purpose of isntalling it on my old pc was to learn linux but this display problem is frustrating me. Thanks, Salman

  • Animating a font size change in a UITableView

    - by nickthedude
    Hey Simple little app for educational purposes, its a simple uitableview and I want users to be able to use a uislider to adjust the font size as needed. The code I have now works to change the font but only when the view is updated, ie when i pull up or down the table view to reveal other cells. I'd like the font change to be reflected immediately as a user moves the uislider if possible, here's the code that I have working half way: -(UITableViewCell *) tableView: (UITableView *)tableView cellForRowAtIndexPath:(NSIndexPath *) indexPath { static NSString *SimpleTableIdentifier = @"SimpleTableIdentifier"; UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier: SimpleTableIdentifier]; if (cell == nil) cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier: SimpleTableIdentifier] autorelease]; NSUInteger row = [indexPath row]; cell.text = [listData objectAtIndex:row]; UIImage *image = [UIImage imageNamed:@"star.png"]; cell.font = [UIFont systemFontOfSize:[fontSlider value]]; cell.image = image; return cell; }

  • Drupal Imagecache not working

    - by stef
    I created an Imagecache setting that just resizes to 125px wide. First issue is that the preview image is 404. Then I want to print out an image via <?php print theme('imagecache', 'imported_image', $node->picture, 'test', 'test', $attributes); ?> 'imported_image' being the preset and $node-picture is a correct path. The html prints out ok but the path it's trying load the image from does not exist. In sites/default/files/imagecache there is no folder with the name of the preset. Flushing the preset does nothing. The imagecache folder is writeable by everyone. This is on MAMP. Anyone know what the issue could be?
